First question
Balaneced:
Find how many moles potassium iodide it is in 345.0 grams
Find how many moles potassium nitrate there is for 2.078 moles 
Find how many grams potassium nitrate there is in 2.078 moles 
Second question
Answer:
it opposes motion. the object would continue to slide forever if not stopped by another object.
On the left (reactant) side you have 6 N-H bonds and 1 Cl-Cl bond
<span>On the right (product) side you have 4 N-H bonds, 1 N-N bond and 2 H-Cl bonds </span>
<span>Add up the bond energies for each side (multiplying by the number of bonds) and calculate the difference for your ΔHº</span>
Answer:
temperature
amount
Explanation:
Under the postulate of Boyle's law, both temperature and amount(number of moles) are kept constant.
According to Boyle's law "the volume of a fixed mass of gas varies inversely as the pressure changes if the temperature is constant"
Based on the premise of this law, both temperature and amount of substance is kept constant.
